|  | 	/** | ||
|  | 		Get a run-time value referencing the `Vector` class with concrete type parameters. | ||
|  | 
 | ||
|  | 		Normally in Haxe, for most of the types, type parameters are eliminated at run-time, | ||
|  | 		so there is no way to check if a value is of a type with specific type parameters. | ||
|  | 
 | ||
|  | 		However, on the Flash target, the `flash.Vector<T>` values carry type parameter | ||
|  | 		information at run-time all the type-checks (such as `Std.isOfType` and `Std.downcast`) on them | ||
|  | 		must be done using a `Class<T>` value that also carries the type parameters. However, | ||
|  | 		Haxe syntax does not allow creating such values and this function exists to mitigate | ||
|  | 		this limitation. | ||
|  | 
 | ||
|  | 		It should be used as such: | ||
|  | 		```haxe | ||
|  | 		var specificVectorType:Class<Vector<Int>> = Vector.typeReference(); | ||
|  | 		trace(Std.isOfType(vec, specificVectorType)); | ||
|  | 		``` | ||
|  | 		or using the type-check syntax: | ||
|  | 		```haxe | ||
|  | 		trace(Std.isOfType(vec, (Vector.typeReference() : Class<Vector<Int>>))); | ||
|  | 		``` | ||
|  | 
 | ||
|  | 		It's also helpful when working with native Flash libraries, that receive Class instances:
 | ||
|  | 		```haxe | ||
|  | 		new Signal((Vector.typeReference() : Class<Vector<Int>>)); | ||
|  | 		``` | ||
|  | 	**/ | ||
|  | 	inline static function typeReference<T>():Class<Vector<T>> { | ||
|  | 		return untyped __vector__(); | ||
|  | 	} | ||
|  | } |
